Irwin 3/32″ Cobalt 135 Degree Jobber Length Drill Bit (63106)

Description

The Irwin 3/32″ Cobalt 135 Degree Jobber Length Drill Bit (63106) is a professional-grade cutting tool engineered to provide exceptional performance and longevity when drilling into the most challenging metal materials. Its specialized construction is centered on a high-speed steel core with a 5% cobalt alloy, which significantly enhances its ability to withstand high temperatures and abrasive friction. This makes it an ideal choice for applications involving hard-to-work materials, where standard drill bits might fail or dull quickly. The bit’s design is optimized for precision and efficiency, featuring a 135-degree split point that ensures it starts drilling instantly without “walking” across the work surface, and a heavy-duty flute that allows for quick and clean chip removal.

KEY FEATURES AND BENEFITS:

• M35 Cobalt Steel Construction: The bit is made from an M35 high-speed steel with 5% cobalt alloy, which provides superior resistance to heat and abrasion, extending the bit’s service life, especially in high-friction applications.
• 135-Degree Split Point: This point geometry ensures that the bit starts drilling immediately upon contact, preventing it from skipping or “walking.” It also reduces the amount of pressure needed to begin cutting and helps prevent work hardening of the material.
• Heavy-Duty Spiral Flute: The flute design is engineered for fast and efficient chip ejection, preventing clogging and allowing for cooler and more consistent cutting performance.
• Straight Shank: The straight shank design ensures compatibility with both standard keyed and keyless drill chucks, making it a versatile addition to any toolbox.

HOW TO USE:

1. Safety First: Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, before operating power tools.
2. Secure Your Workpiece: Firmly clamp the material you are drilling to a stable surface to prevent movement during operation.
3. Install the Bit: Insert the straight shank of the Irwin 63106 drill bit into your drill’s chuck. Make sure the bit is centered and securely tightened to prevent it from slipping.
4. Set the Speed: Select an appropriate drill speed for the material you are working on. Hard metals like stainless steel require a slower speed than softer materials to prevent overheating.
5. Begin Drilling: Place the tip of the drill bit on the desired mark. Apply steady, firm pressure to start the drilling process. The 135-degree split point will help the bit start cleanly without walking.
6. Maintain Pressure and Coolant: Keep consistent pressure on the bit throughout the process. For especially tough materials, use a cutting fluid or lubricant to help cool the bit and prolong its life.
7. Clear Chips: Allow the heavy-duty flutes to clear the chips as you drill. If necessary, pull the bit out periodically to clear excess debris.
